Create Coherence servers

Coherence servers (also known as Coherence data nodes) are stand-alone cache servers, dedicated JVM instances responsible for maintaining and managing cached data.

To create a Coherence server in an existing domain:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the left pane of the Console, expand Environment and select Coherence Servers.
  3. In the Coherence Servers table, click New.
  4. On the Coherence Server Properties page:
    1. Enter the name of the server in the Name field.

      The server name is not used as part of the URL for applications that are deployed on the server. It is for your identification purposes only. The server name displays in the Administration Console, and if you use WebLogic Server command-line utilities or APIs, you use this name to identify the server.

    2. Select an existing Machine (WebLogic Server host computer name on which this server is meant to run) from the drop-down list.

      In order to use Node Manager to start this Coherence server, you must assign the server to a machine and you configure the machine for the Node Manager. See Create and configure machines.

    3. Optional. In Cluster, enter the system-level Coherence cluster resource associated with this server.
    4. Optional. In Unicast Listen Address, enter the IP address for the cluster unicast listener. This attribute may be used to override the value of the referenced Coherence cluster.
    5. Optional. In Unicast Listen Port, enter the port for the cluster unicast listener.
    6. Optional. Use the Unicast Port Auto Adjust check box to specify whether the unicast port will be automatically incremented if the port cannot be bound because it is already in use.
  5. Click Finish.

    The new server appears in the Summary of Coherence Servers table.

  6. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).

After you finish

(Optional) Do any of the following:
